I had high hopes for these flakes, but I'm afraid they taste a bit odd to me. Even putting them as "cheese" on some foods, there is just something different about them that makes them more of a distraction than an actual part of the food. I doubt I'll order them again. (By the way, I have very sensitive taste buds, so I am rather picky about food.)

I read multiple times people describing the taste as parmesan-cheese like. I'm confused, because it really tastes nothing like parmesan, wich is why I bought it. I was really disappointed.
But as far as yeast goes, the taste is not bitter at all.
